Specification of Letters Patent.

Patented Jan, 9, 1906.

Application filed May 15,1905. Serial No. 260,5 96.

To all whom, it TIMLZ/ concern:

Be it known that I, NEAL MGLAUGi-ILIN, a citizen of the United States,residing at Jethro, in the county of Franklin and State of Arkansas,have invented certain new and useful Improvements in aCombined Scraperand Shovel- Plow', of which the following is a specification, referencebeing had therein to the accompanying drawings.

My invention relates to improvements in combined scrapers andshovel-plows, and pertains more particularly to the adjustment of thescraper.

The object of my invention is to provide a scraper of this characterwhich is provided with two cutting edges which are precisely alike andwhich are interchangeable, so that either edge may be used when desiredor necessary.

Another object of my invention is to provide a scraper of this characterin which a smooth outer dirt-engaging surface is maintained and at thesame time having the same adjustable and interchangeable, so that eithercutting edge may be brought into action and either end may be raised orlowered; also, to provide means whereby the holding means is adjustableon the standard, and thus the blade may be set transverse the beam or atany angle desired.

In the accompanying drawings, Figure 1 is aperspective view of myimproved scraper and shovel-plow. Fig. 2 is an enlarged side elevationof my improved blade-attaching means. Fig. 3 is a transverse horizontalsectional view of the blade-attaching means. Fig. 4. is a perspectiveview of the blade-attaching device detached.

Referring now to the drawings, A represents a plow-beam which, as shown,is formed of the two rearwardly-extending arms B and B, which have theirrear ends turned downward at b and b. The downwardly-turned end 6 of themember B is made of a circular form, as clearly shown in Fig. 2, andwhich will be hereinafter more fully described. The downwardly-extendingend I) of the arm B is squared, and secured thereto is the shovel-plow(1, which may be of any desired structure, but is preferably made ofthat shown and so arranged that it may be adjusted up or down or at anyangle desired. This adjustment is accomplished by the said shovel-plowbeing provided with a vertical slot 0, and passing through said slot andthe arm 6' is a bolt D, which firmly holds the shovel-plow in itsadjusted position.

The lower end of the arm 6, as before described, is'rounded for thepurpose of allowing the blade-supporting member to be oscillated thereonwhen the holding means is released. The blade supporting or attachingmember consists of an oblong plate E, and which may be either cast or ofsheet metal stamped, the latter being the preferred form, as it is lessliable to become broken. The said plate E consists of a curved portionF, which is of a curvature to correspond to that of the blade G, and isprovided adjacent the upper end with a segmental slotf", and the blade Gis provided adjacent each end with two openings g and spaced a distanceapart equal to the openings f and f, and passing through the blade arethe bolts H and H. The bolt H forms the pivotal point for the blade, andthe lower bolt H passes through the slot f in the plate and is adaptedto travel in the are of a circle, and thus the blade is adjusted andheld in its adjusted position.

The blade G, as clearly shown, is provided adjacent the center with theopenings 9 and g, and thus the blade can be reversed, so that either thecutting edgesJ or J may be brought into action, which makes the bladelast much longer than with a blade with a single cutting edge.

The plate E is provided with a vertically-disposed curved portion I,which is curved at right angles to the curved blade-engaging portion, soas to fit the curvature of the rounded portion Z) of the beam, and thesaid rounded portion has a horizontally-arranged elongated slot '27, andpassing through said slot from the outside before the blade is placedupon the plate is a bolt K, which passes through the rounded portion 5of the beam and by means of which the said plate is clamped thereto. Itwill be seen by loosening the bolt that the plate may be oscillated uponthe memberb to the extent of the slot, and by this means the angle ofthe blade is changed in respect to the plow-beam. The lower end of thecurved portion I has a forwardly-turned portion L, which extends forwardand engages the blades, thus serving as an additional brace for theblade and also serving as a brace for the plate to absolutely preventthe same from being twisted out of its normal shape.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. A scraper, comprising a draft-beam, a downwardly-extending armcarried by the beam and having its lower end rounded, a

blade-supporting member having a curved.

portion corresporiding to the curve of the beam, means for clamping saidplate on the arm, means carried by the plate for securing the bladethereto, and aforWardly-turned portion carried by the curved portion ofthe plate for engaging and bracing the blade.

2. A scraper, comprising a draft-beam, a downwardly-extending armcarried by the beam and having its lower end rounded, a blade-supportingmember having a verticallydisposed curved portion resting against thearm, and having a horizontal elongated slot therein, a bolt passingthrough the slot and clamping the plate to the arm, one side of saidcurved portion having a laterally-turned blade-supporting surface, meansfor adjustably holding the blade thereon, and the opposite edge of saidcurved portion having a laterally-turned portion engaging the blade andbracing the same.

3. A scraper, comprising a draft-beam, a downwardly-extending armcarried by the beam and having its lower end rounded, a

blade-supporting member having a verticallydisposed curved endcorresponding to the rounded end of the arm and resting against thesame, and having a horizontal elongated slot therein intermediate theupper and lower ends, abolt passing through the slot and arm andsecuring the plate to the arm, one side of said curved portion havingaforwardly-turned elongated blade-supporting portion, means for NEALMGLAUGHLIN.
